A man named Tacitus wrote a famous set of books. 

The Annals is a famous set of history books. 

Tacitus wrote about how the empire was run. He started his story in AD 14. This was when Augustus Caesar died. He then wrote about the leader Tiberius. The books follow the empire year by year. This is why we call them "Annals." He used official records from the Roman senate. These records are called Acta Senatus. Using these files helped him tell a true story. He wanted to show how the government worked.
Writing these books was a big job. Tacitus wrote at least 16 books for the Annals. He also wrote another set called the Histories. Together, these two works made 30 books. We do not have all of them now. Only about half of the books survived. Some parts are missing from the middle. For example, books 7 through 10 are gone. We also lost parts of books 5 and 6. The story ends in the middle of AD 66.



The *Annals* is a foundational work of Roman historiography. It was written by Cornelius Tacitus, a prominent Roman senator and historian. This work provides a detailed history of the Roman Empire during the first century AD. Specifically, it covers the era from the death of Augustus Caesar in AD 14 to the end of Nero's reign in AD 68. Modern historians often consider the *Annals* to be Tacitus's magnum opus. This term describes a creator's greatest or most important work. Historian Ronald Mellor even called it the "pinnacle of Roman historical writing." 
Tacitus used a specific structure to organize his history. The title *Annals* comes from this year-by-year format. While Tacitus referred to parts of his writing as "my annals," he did not name the work that way himself. To ensure accuracy, Tacitus likely used the *Acta Senatus*. These were the official records of the Roman senate. As a senator, he had direct access to these important documents. This gave his historical narrative a very solid and reliable basis.
At its peak, Tacitus's historical writings were massive. He wrote the *Histories* and the *Annals*, which together totaled 30 books. Scholars traditionally divide these into 14 books for the *Histories* and 16 for the *Annals*. However, some scholars disagree on which books belong to which work. We do not have the full collection today. According to the writings of Saint Jerome, about half of these 30 books have survived. This means much of Tacitus's original detail is lost to time.
The surviving books of the *Annals* follow the reigns of several emperors. The first six books cover the reign of Tiberius. These are divided into two sets of three books. This division reflects changes in the political climate during his rule. Books 11 and 12 cover the end of Claudius's reign, including the actions of Messalina. The final four books focus on the emperor Nero. Unfortunately, large sections are missing. Books 7 through 10 are completely lost. We also lack parts of books 5, 6, 11, and 16. Because Book 16 cuts off in AD 66, we have lost the final two years of Nero's reign.
Tacitus used his writing to explore the Roman imperial system. He presented a complex view of the transition from the Republic to the Principate. He noted that Augustus Caesar brought peace after years of civil war. However, Tacitus also highlighted the "dark side" of life under the Caesars. He observed the loss of political freedom for the senatorial aristocracy. He viewed this group as morally decadent and corrupt. He portrayed Tiberius and Nero as tyrants who ruled through fear. While he saw Tiberius as a man who was once great, he described Nero as simply despicable. 
The history of how these books were found is quite interesting. The manuscripts have roots in the Renaissance period. Some parts, specifically Books 11 through 16, were likely kept at Monte Cassino. The writer Giovanni Boccaccio may have moved these copies to Florence. In 1508, Giovanni Angelo Arcimboldi discovered Books 1 through 6 at Corvey Abbey in Germany. 
Today, the *Annals* remains a significant part of global culture. You can find references to Tacitus in many modern works. For instance, the character Berlioz in *The Master and Margarita* discusses the text. The character Yu Tsun is seen reading the *Annals* in a short story by Jorge Luis Borges. Even in detective novels like Donna Leon's *Dressed for Death*, the books appear. The *Annals* connects us to the political struggles and the famous figures of ancient Rome. It remains a vital tool for anyone studying the history of the ancient world.
